Coronavirus disease 2019 (COVID-19), a mystified cryptic virus has challenged the mankind that has brought life to a standstill. Catastrophic loss of life, perplexed healthcare system and the downfall of global economy are some of the outcomes of this pandemic. Humans are raging a war with an unknown enemy. ⋯ Theoretically and practically, researchers have observed that persons with pre-existing cardiovascular conditions are comparatively more vulnerable to the COVID-19 infection. Moreover, they have studied the data between less severe and more severe cases, survivors and non survivors, intensive care unit (ICU) patients and non ICU patients, to analyse the relationship and the influence of COVID-19 on cardiovascular health of an individual, further the risk of susceptibility to submit to the virus. This review aims to provide a comprehensive particular on the possible effects, either direct or indirect, of COVID-19 on the cardiovascular heath of an individual.

Social Media usage has been shown to increase in situations of natural disaster and other crises. It is crucial for the scientific community to understand how social media works in order to enhance our capabilities and make a more resilient community. Through social media communication, the scientific community can collaborate around the globe in a faster way the most important findings of a disease, with a decreased knowledge transition time to other healthcare providers (HCPs). ⋯ A major limitation of social media currently is the ability to quickly disseminate false information which can confuse and distract. Society relies on educated scientists and physicians to be leaders in delivering fact-based information to the public. For this reason, in times of crises it is important to be leaders in the conversation of social media to guide correct and helpful information and knowledge to the masses looking for answers.

Review
Endothelial dysfunction contributes to COVID-19-associated vascular inflammation and coagulopathy.
Great attention has been paid to endothelial dysfunction (ED) in coronavirus disease 2019 (COVID-19). There is growing evidence to suggest that the angiotensin converting enzyme 2 receptor (ACE2 receptor) is expressed on endothelial cells (ECs) in the lung, heart, kidney, and intestine, particularly in systemic vessels (small and large arteries, veins, venules, and capillaries). Upon viral infection of ECs by severe acute respiratory syndrome coronarvirus 2 (SARS-CoV-2), ECs become activated and dysfunctional. ⋯ Therefore, it is reasonable to assume that ED contributes to COVID-19-associated vascular inflammation, particularly endotheliitis, in the lung, heart, and kidney, as well as COVID-19-associated coagulopathy, particularly pulmonary fibrinous microthrombi in the alveolar capillaries. Here we present an update on ED-relevant vasculopathy in COVID-19. Further research for ED in COVID-19 patients is warranted to understand therapeutic opportunities.

Serum albumin in patients undergoing transcatheter aortic valve replacement: A meta-analysis.
Transcatheter aortic valve replacement is becoming a more common therapeutic option for the treatment of aortic stenosis in patients at high risk for invasive surgery, but detecting which patients will benefit clinically can be challenging. Hypoalbuminemia is a useful prognostic marker for chronic inflammation in this population. We carried out a systematic review and meta-analysis of studies evaluating the prognostic value of serum albumin level in patients undergoing transcatheter aortic valve replacement. ⋯ A sub-group analysis of eight studies reporting adjusted hazard ratios indicated that low serum albumin was independently correlated with increased post-operative mortality. The hazard ratio of mortality risk associated with each 1 g/dL increment in serum albumin level was 0.46, suggesting a potential dose-response relationship between increased serum albumin level and increased survival rate in patients undergoing transcatheter aortic valve replacement. This meta-analysis provides strong evidence for the utility of serum albumin as a prognostic marker in aortic stenosis patients undergoing transcatheter aortic valve replacement, with low serum albumin levels (2.5-3.5 g/dL) suggesting poor prognosis.

In this systematic review, we sought to summarize the 3 recent sodium-glucose cotransporter 2 inhibitor (SGLT2i) trials (Dapagliflozin Effect on CardiovasculAR Events (DECLARE-TIMI 58), Canagliflozin Cardiovascular Assessment Study (CANVAS) Program, and Empagliflozin, Cardiovascular Outcomes, and Mortality in Type 2 Diabetes (EMPA-REG OUTCOME)) and to explore the potential causes for their different results. We found that the major adverse cardiovascular event rates per 1000 patient-years for drug and placebo, as well as the corresponding relative risk reductions, were 22.6, 24.2, 7%; 26.9, 31.5, 14%; 37.4, 43.9, 14% for DECLARE-TIMI 58, CANVAS, and EMPA-REG OUTCOME, respectively. DECLARETIMI 58 had the fewest cardiorenal events (across treatment and control arms) and EMPA-REG OUTCOME the most. ⋯ Therefore, the DECLARE-TIMI 58 study cohort had higher eGFR (mean eGFR 85.2 mL/min/1.73 m2 compared to 76.5 and 74 in CANVAS and EMPAREG OUTCOME, respectively); this may have caused the difference in results. Additionally contributing to the high event rate in EMPA-REG OUTCOME was the requirement of prior confirmed cardiovascular disease (CVD), resulting in 99.2% of patients with CVD compared to only 65.6% and 40.6% in CANVAS and DECLARE-TIMI 58, respectively (which did not require CVD). In conclusion, there is a need for large-scale studies of SGLT2i with matching inclusion/exclusion criteria and appropriate endpoints to ensure a truly direct comparison of the drugs.
